Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Report qualification: CNAS, CMA, CAL, etc.
Testing costs: Quotation sample size according to customer needs and experimental
complexity: Choose to send samples or come to the door according to the sample size
Scope
This part of GB/T17626 specifies the immunity test methods and preferred test level ranges for electrical and electronic equipment connected to low-voltage power supply networks to voltage dips, short interruptions, and voltage changes This section applies to electrical and electronic equipment with a rated input current of no more than 16 A per phase connected to a 50 Hz or 60 Hz AC network This section does not apply to electrical and electronic equipment connected to a 400Hz AC network. The testing of these networks will be covered in future standards The purpose of this section is to establish a general criterion for evaluating the immunity of electrical and electronic equipment to voltage dips, short interruptions, and voltage changes Note: Voltage fluctuation immunity test can be found in GB/T 17626 The test methods specified in this part of GB/T17626 provide a consistent method for evaluating the immunity of equipment or systems to defined electromagnetic phenomena. As stated in GB/Z18509-2001, this is an EMC foundational publication used by the IEC Professional Standardization Technical Committee. As stated in GB/Z18509-2001, the relevant professional standardization technical committee is responsible for determining whether this immunity standard is applicable, and if applicable, for determining the appropriate test level and performance criteria. The EMC Standardization Technical Committee and its subcommittees are preparing to collaborate with relevant professional standardization technical committees to evaluate specific immunity test values for their products
